ConnectX-5, utilizing IBTA RDMA (Remote Data Memory Access) and
RoCE (RDMA over Converged Ethernet) technology, delivers low-
latency and high-performance over Band and Ethernet networks.
Leveraging data center bridging (DCB) capabilities as well as
ConnectX-5 advanced congestion control hardware mechanisms,
RoCE provides efficient low-latency RDMA services over Layer 2 and
Layer 3 networks.
PeerDirect™ communication provides high-efficiency RDMA access
by eliminating unnecessary internal data copies between
components on the PCIe bus (for example, from GPU to CPU), and
therefore significantly reduces application run time. ConnectX-5
advanced acceleration technology enables higher cluster efficiency
and scalability to tens of thousands of nodes.
Adapter functionality enabling reduced CPU overhead allowing more
available CPU for computation tasks.
Open vSwitch (OVS) offload using ASAP
• Flexible match-action flow tables
• Tunneling encapsulation/decapsulation
Support for port-based Quality of Service enabling various
application requirements for latency and SLA.
ConnectX-5 provides dedicated adapter resources and guaranteed
isolation and protection for virtual machines within the server.
A consolidated compute and storage network achieves significant
cost-performance advantages over multi-fabric networks. Standard
block and file access protocols can leverage RDMA for high-
performance storage access.
• NVMe over Fabric offloads for the target machine
• T10-DIF Signature Handover
ConnectX-5 SR-IOV technology provides dedicated adapter
resources and guaranteed isolation and protection for virtual
machines (VM) within the server.
The adapter supports a Network Controller Sideband Interface (NC-
SI), MCTP over SMBus and MCTP over PCIe - Baseboard
Management Controller interface.
• Tag Matching and Rendezvous Offloads
• Adaptive Routing on Reliable Transport
• Burst Buffer Offloads for Background Checkpointing
